+;; Author: William Carroll <wpcarro@gmail.com>

+;;; Commentary:
+;; These functions are intended to be bound to KBDs for daily use and
+;; refactoring.
+
+;;; Code:
+
+(require 's)
+(require 'dash)
+
+;; todo - grab the string at point and replace it with the output of
+;; each fn
+
+(defun caps->kebab (x)
+  "Change the casing of X from CAP_CASE to kebab-case."
+  (->> x
+       s-downcase
+       (s-replace "_" "-")))
+
+(defun kebab->caps (x)
+  "Change the casing of X from CAP_CASE to kebab-case."
+  (->> x
+       s-upcase
+       (s-replace "-" "_")))
+
+;;; Tests:
+
+(ert-deftest caps->kebab-test ()
+  (should (string= (caps->kebab "CAPS_CASE_STRING")
+                   "caps-case-string")))
